[0059] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In the description of the present invention, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally disposed component. When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally disposed component.

[0061] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0062] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0063] The present invention provides a crown testing fixture with a button lever structure, which is suitable for application scenarios where electrical testing of a crown assembly is performed. The crown body of the crown assembly can be clamped and then an FPC cable of the crown assembly can be electrically tested, which is beneficial to improving testing efficiency.

[0064] See also Figure 1 to Figure 3 In this embodiment, the crown testing fixture of the button lever structure includes a fixture assembly 1, a clamping mechanism 2 and a rotating cover plate 3.

[0065] The fixture assembly 1 includes a fixture body 101 having a receiving groove, a carrier plate 102 located in the receiving groove, a sliding hook plate 103 , a cover spring 104 , an auxiliary stopper 105 and an L-shaped member 106 .

[0066] The upper surface of the carrier plate 102 is provided with a test slot 1021 for inserting the FPC cable of the crown assembly 4; the rotating cover plate 3 is located above the carrier plate 102 and is hinged to the fixture body 101, and is used to press the FPC cable downward into the test slot 1021. The sliding hook plate 103 is located beside the receiving groove; when the rotating cover plate 3 presses the FPC cable, the cover plate spring 104 drives the sliding hook plate 103 to slide to the top of the rotating cover plate 3, restricting the rotating cover plate 3 from rotating upward, maintaining the tight pressure on the FPC cable, and thus ensuring the stability of the test process.

[0067] See also Figures 4 to 6In this embodiment, a limiting boss 1011 protrudes from the inner side of the fixture body 101. Specifically, the limiting boss 1011 is located above the carrier 102. The auxiliary stopper 105 is installed on the carrier 102 and forms an insertion space with the carrier 102. The L-shaped member 106 includes a vertical portion 1061 and a horizontal portion 1062 that is laterally inserted into the insertion space. The vertical portion 1061 is provided with a clearance groove 10611 for the limiting boss 1011 to be laterally inserted.

[0068] It is understandable that when installing the carrier 102 and the fixture body 101, the carrier 102 is first placed in the receiving groove, and then the L-shaped piece 106 is inserted horizontally into the insertion space. The L-shaped piece 106 can limit the upward movement of the carrier 102, thereby achieving the positioning of the carrier 102. Optionally, a positioning magnet 107 is provided on the carrier 102, and an iron block magnetically connected to the positioning magnet 107 is provided at the bottom of the L-shaped piece 106. When the L-shaped piece 106 is inserted horizontally into the insertion space, the iron block at the bottom of the L-shaped piece 106 is just opposite to the positioning magnet 107, thereby achieving the positioning of the L-shaped piece 106. When the carrier 102 needs to be disassembled, the magnetic force of the positioning magnet 107 is first overcome, and the L-shaped piece 106 is pulled out horizontally, and then the carrier 102 can be taken out.

[0069] In this embodiment, the clamping mechanism 2 is installed on the side of the fixture body 101 to clamp the crown body of the crown assembly 4. Optionally, the clamping mechanism 2 includes a fixed clamping block 201, a movable clamping block 202, a clamping spring 203, a lever member 204 and a push handle assembly 205.

[0070] Among them, the fixed clamping block 201 is fixed on the jig body 101; the movable clamping block 202 is arranged opposite to the fixed clamping block 201, and is slidably connected to the jig body 101; the clamping spring 203 is located on the side of the movable clamping block 202 away from the fixed clamping block 201, and is used to drive the movable clamping block 202 to slide toward the fixed clamping block 201 to cooperate with the fixed clamping block 201 to clamp the crown body; one end of the lever member 204 is abutted against the movable clamping block 202, the middle part is hinged to the jig body 101 through a rotating shaft, and the other end is connected to the push handle assembly 205; the push handle assembly 205 is used to drive the lever member 204 to rotate, so that the movable clamping block 202 slides in the direction away from the fixed clamping block 201.

[0071] See also Figure 7Optionally, the push handle assembly 205 includes a push handle body 2051, a positioning pin 2052, a positioning spring 2053 and an elastic button. The push handle body 2051 is connected to the lever member 204, and a button compartment is provided inside the push handle body 2051; the upper end of the positioning pin 2052 extends into the button compartment, and the lower end extends to the bottom of the push handle body 2051; the positioning pin 2052 is connected to the push handle body 2051 for vertical sliding; the positioning spring 2053 is located in the button compartment, and is used to drive the positioning pin 2052 to slide downward to enter the positioning hole 1012 on the fixture body 101; the elastic button is installed at the button compartment, and is used to drive the positioning pin 2052 to slide upward to disengage from the positioning hole 1012.

[0072] The elastic key comprises a pressing block 2054 and a key spring 2055. One end of the pressing block 2054 extends into the key compartment, and the other end extends to the outside of the key compartment; the pressing block 2054 is slidably connected to the push handle body 2051 in the horizontal direction; the end of the pressing block 2054 close to the positioning latch 2052 is provided with a first inclined surface 20541 facing obliquely upward; the upper part of the positioning latch 2052 is provided with a second inclined surface 20521 extending above the first inclined surface 20541 and slidably connected to the first inclined surface 20541; the key spring 2055 is located in the key compartment, and is used to drive the pressing block 2054 to slide in a direction away from the positioning latch 2052.

[0073] The crown test fixture of the button lever structure provided in this embodiment has the following working process:

[0074] S10: Overcoming the elastic force of the cover plate spring 104, pushing the sliding hook plate 103 backward, opening the rotating cover plate 3, and exposing the receiving groove;

[0075] S20: Place the carrier plate 102 with the auxiliary stopper 105 installed in the receiving groove, and then push the L-shaped piece 106 into the space laterally. Under the magnetic force of the positioning magnet 107, the L-shaped piece 106 is positioned, and the assembly of the carrier plate 102 and the fixture body 101 is completed;

[0076] S30: Push the push handle assembly 205 to drive the end of the lever member 204 close to the active clamp block 202 to rotate in the direction close to the clamping spring 203, thereby squeezing the clamping spring 203 and forcing the active clamp plate to slide in the direction away from the fixed clamp plate;

[0077] It should be noted that, during the rotation of the lever member 204, the positioning pin 2052 also keeps sliding on the fixture body 101; until the lever member rotates to the limit position, the positioning pin 2052 is just aligned with the positioning hole 1012 on the fixture body 101, and then slides downward and is inserted into the positioning hole 1012 under the action of the positioning spring 2053; at this time, even if the push handle assembly 205 is released, the lever member 204 can maintain the state of compressing the clamping spring 203, so as to make room for the subsequent operation of placing the crown assembly 4 between the fixed clamp block 201 and the movable clamp block 202;

[0078] S40: The crown body of the crown assembly 4 is placed between the fixed clamp block 201 and the movable clamp block 202, and then the pressing block 2054 is pressed inward to overcome the elastic force of the key spring 2055. When the pressing block 2054 slides toward the positioning pin 2052, the positioning pin 2052 is guided by the first inclined surface 20541 and the second inclined surface 20521, and slides upward and disengages from the positioning hole 1012;

[0079] Then, under the elastic force of the clamping spring 203, the lever 204 drives the handle assembly 205 to rotate in the opposite direction around the rotation axis, and the movable clamp block 202 then slides toward the fixed clamp block 201 until the fixed clamp block 201 clamps the crown between the fixed clamp block 201 and the movable clamp block 202;

[0080] S50: insert the FPC cable into the test slot 1021 of the carrier board 102, and then cover the rotating cover plate 3, the cover plate spring 104 drives the sliding hook plate 103 to press the rotating cover plate 3, and then press the FPC cable to ensure the stability of the test process;

[0081] S60: After the test is completed, open the rotating cover 3, pull out the FPC cable, and then rotate the push handle assembly 205 again to take out the crown body.

[0082] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0083] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
